Surface Technology
Our expertise in door surface design and treatment allows customers to choose from a variety of styles, including wood grain finish, sky blue paint, and nearly any style in between. Request a door catalogue, and you can view color options, pattern options, and finish options.

Main Lock
The main lock is perhaps the most important part of a doorway to protect your space. This is whySimto installs high quality, double locks that are extremely difficult to pick, to deter even the most determined intruders.

Through extensive testing, it has been determined that it takes at least 300 minutes to open the lock using a method other than the key. Property owners can open and close the main lock from both inside and outside the property. To further deter intruders, the weak points on the lock have been reinforced with a protective shield.

Secondary Lock
The secondary lock system includes two round dead bolts that can only be used when you are home, as they are engaged from the inside. They can’t be opened using the key when standing outside the steel security door. These one-sided keyless deadbolts are adhered tightly to the door jamb, and actually installed in the door frame for added security. Their strike plates are also covered with a protective shield.

At Simto, we check the quality at each step of the door production, from the conception of an idea to the finished door. An optimized work flow, top equipment, quality materials and stringent quality control checks ensure that door buyers get the best for their money. Each of our interior doors is built to exceed GB17565-2007 standards. Please feel free to contact us for more details.
